APPARATUS FOR SPINNING MECHANISM.

Specification of Letters Patent. Patented Feb. 15, 1916.

Application filed July 8, 1913. Serial No. 777,870.

To all whom it may] concern Be it known that I, DAVID S. SEAMAN, a citizen of the United States, residing at Providence, in the State of Rhode Island, have invented new and useful Improve ments in Apparatus for Spinning Mechan ism, of which the following is a specificatron.

This invention relates to spinning mechan isms and has particular reference to improvements in processes and apparatus for filling bobbins.

The object of the invention is to produce a spinning mechanism by which more than double the usual amount of yarn maybe wound upon each bobbin and thereby reduce the number of doffers required and also make possiblethe further elimination of labor in the subsequent twisting opera tions.

Referring to the drawings: Figure 1 is an elevation of an improved spinning spindle, bobbin and cap; Fig. 2 is a sectional elevation of the same mechanism; Fig. 3 is a similar view showing the parts in a different position; Fig. A is a sectional elevation of an ordinary bobbin after the yarn has been wound thereon; Fig. 5 is a section taken on the line 55 of Fig. 3; and Fig. 6 is a section taken on the line 66 of Fig. 2. I

The ordinary bobbin usually constructed of wood is shown at 10 in Fig. 1, and as there indicated, is wound with the distinct sections of yarn numbered in their order of winding from 1 to 5 inclusive, this being the ordinary bobbin and ordinary winding. The bobbin is supported and driven by a sleeve and pulley 11, indicated in Figs. 1,

2 and 8, through which passes the spindle 12 which carries at its upper extremity the cap 13. A pot-eye indicated at 14 in Fig. 1 forms a guide through which the yarn is passed to the winding bobbin.

In the usual method of winding bobbins such as the one shown in Fig. 1, the spinning sleeve 11 rotates the bobbin, after the yarn 15 is attached thereto; and the cap 13 at the beginning of the operation encircles the bobbin, it being moved to its lowest position by the spindle 12, the yarn passing through the pot-eye and under the lower rim of the cap onto the bobbin. The spindle 12 and cap 13 are given a reciprocating motion upward and downward, so that the yarn is wound upon the bobbin in the section indicated at 1 in Fig. 4, The movement of the spindle l2 and cap 15 is governed bymechanism well known in the art (not here claimed or shown). After section 1 has been wound upon the bobbin, the spindle 12 shifts its position so that its rec procations take place at a higher elevation and the yarn is wound on the bobbin as shown in section 2. This general method is continued until all five sections of the bobbin are wound.

It will be noticed that section 1 is so wound that the yarn lies closely against a shoulder 16 on the bobbin and tapers ofi at the upper part of the section, and that each of the other sections has a symmetrical, angular winding, as .clearly shown in the figure. In ordinary practice the depth of this winding is usually something less than of an inch. In themachinesheretofore in use it has not been practicable to wind the yarn upon the bobbin to a greater depth than this, as in the winding operation the strain which is put upon the yarn as it passes from the edge 17 of the cap to the core of the bobbin is so greatthat the yarn will break if this distance be increased to anything more than about 3 The distance of the pot-eye from this lower rim' of the cap is immaterial, it may be increased or diminished at will; but the distance from the lower rim of the cap to the bobbin i limited and fixed for the reason given. It

.is because of this limitation that the winding on the'bobbin is usually of no greater depth than about a to as there must be clearance between the winding and the lower part of the cap.

In the improved structure the cap is equipped with a vertical slot 18 having an oflset aperture 19 at its top and an annular skirt 20 is slipped over the cap 13 and by means of screws 21 on opposite sides it on gages the slot 18 and is held in place upon the cap. In Fig. 3 the cap is shown in its upper position, to which it has been raised by hand and given a slight turn to the right, as viewed in that figure, so that the screws 21 rest in the aperture 19, something in the manner of a bayonet joint. As indicated in that figure, the bobbin has been wound with the usual five sections of yarn, the integral lower rim of the cap 13 having served as an annular guide for the yarn. After this first winding has been completed, the cap 20 is given a slight turn to the left and is allowed to drop to the bottom of the slot 18 in which position it is shown in Figs. 1 and 2. The lower rim 22 of this skirt 20 is now in position to guide the yarn upon the'bobbin'; the spindle 12 and cap 13 are lowered as before and the winding operation is repeated. A second layer of sections numbered '6 to 10; inclusive, are then wound over the first layer, so that the bobbin is wound with more than double the usual amount of yarn. The proportions of the skirt 20 with its rim 22 are such that the distance from the rim 22 m the first layer of the bobbin Winding is substantially the same as thedistance of the lower rim 17 of the skirt 10 to the bobbin,

so that the winding takes place in the second operation under the same conditions as in the first, so far as the strain u'poii the yarn is concerned. The vertical dimension or the skirt is such that it can cover the whole of the section which is being wound under it.

Referring toFig, 4, it will be noticed that the fifth section of the winding is tapered, and the outeryarn liesfin a conical winding due to the method-of winding and tothe cylindrical core of the bobbin. If the bobbin having such a cylindrical core were used in connection with the skirt 20, the

yarnwould break at this point because the distance from the rim' 22 0f the skirt to the bobbin would be considerably more than a". To prevent such break and to permit the use of the skirt 20, the bobbin is given the special form indicated in Figs. 2 and 3.

The bobbin there shown has the u's'u'at shoul'-.

d er' at lower end,- and is cylindrical for the greater part of its length to the part 23 Where the fifth section is wound uponit; at this point it is given the outward taper 28, the angle being substantially the same as the angle of the winding of section 5". Because" of this taper 23 the conical lay of the fifth section of the layer is compensated for, with the result that the first five sections WOLTfld upon the bobbin form a cylindrical shape as shown in Figs. 2' 3 instead of (topics of a cylinder having a cone-shaped end as in of the bobbin, the distance from the first:

layer to the skirt rim 22 is always such as to enable the second layer to be wound in full upon" the bobbin without breaking o the yam.

hat is claimed:

1. In combination, a spinning cap having its lower rim adapted to serve as a yarn guide, a-skirt a'ttached to the cap'and having its lower rim also adapted to operate as a yarn guide, and means for adjusting the sl'iirt into and out of operative position.

2'. In combination, a spinning cap having its lower rim adapted to serve as a yarn guide, a skirt attached to-the cap and having its lower-rim of greater diameter than the cap rim and also adapted to operate as a yarn guide, and means for adjusting the skirt into and out of operative position In combination, a spinning cap equipped with a plurality of yarn guide rims, and adjusting means whereby any one of the gui' le rims may be placed in operative position.

4. Injcombijnation, a cap having an integral rim forming a yarn guide, and a skirt attached to the cap and having an integral rim adapted to form a yarn guide, the cap rim and the skirt rim being adapted to operate in alternative order.

In combination, a spinning cap having a its lower rim adapted to serve as a yarn guide, a slot located in the cap, a skirt sur-v rounding the cap' and engaging the slot, the skirt having a flaring rim adapted to serve as a yarng'uide and being movable within the said slot, so that it may be held out of operative position; 7 7
